Abstract

C. Macfie Campbell The review of two patients presenting the combination or alter-nation of manic-depressive and schizophrenic modes of reaction. The constitution of the patients may have determined to a certain extent the type of their reaction, but early environment and experiences had probably influenced their stability and left their stamp on the later psychoses. A fatalistic emphasis on the congenital endowment is less useful than attention to the moulding environmental factors, the study of which encourages effort in the direction both of prophylaxis and treatment.
